Answer:

Step-by-step explanation:
Remember that the sides of a cube always have the same length.
In this case the length of the sides L is:
.
The cubes have 6 faces. Then the surface area of the cube is equal to the area of its 6 faces.
Since all sides of the cube have the same measure, then the area of each face is:

Then the area of the 6 faces is:

Answer:
there were 82 adult tickets and 32 children tickets that were sold
Step-by-step explanation:
x = adult's tickets
y = children's tickets

x + y = 114
y = -x +114
replace y by -x +114 in the second equation
11x + 6y = 1094
11x + 6(-x + 114) = 1094
11x -6x + 684 = 1094
5x + 684 = 1094
5x = 410
x = 82
x + y = 114
82 + y = 114
y = 32
